This USB cable adds a DB9 serial port to your computer or laptop. Works with MacOS X, Linux and Windows. Note that this provides (approximately) +-10V serial (RS232) not 5V serial (TTL), good for old devices like GPS, handhelds, programmers, etc with chunky DB9's on the side. Some cheaper RS232 cables 'cheat' and only give you 0-5V which wont work with some devices - this one has a true voltage doubler/inverter to make it more compatible.
These are tested and work great with bit-bang serial devises MiniPOVs, DASA programmers and Serial SpokePOV adapters - note that they are slow in comparison to hardware serial ports due to the high overhead of USB.
They are super fast for every day USB-Serial conversion. Uses the PL2303 chipset. Comes with a CD but I strongly suggest using the
most recent drivers from the Prolific Website if you're running windows and
the 'fixed' driver for Mac OSX or
the version for MacOS 64 bit. If you're using Windows 7 and you have issues, try the Prolific driver version 1.013
